200 IoT Applications — Value Creation for Industry
WiMon 100
The outcome of the project was an ABB product called the WiMon 100. It is
a battery operated device with an expected lifetime of five years that intends
to reduce the cost of maintenance as well as extend the lifetime of electric
motors. The sensor is Ex-proof and is ideal for use in the offshore sector. In
principle, however, it can be used in all industrial sectors with the same benefits.
The product uses the new WirelessHART communications protocol, which
was ratified in September 2007. The Wireless Vibration system delivers a cost
effective, secure and reliable data acquisition, analysis, and sharing of real time
information. The small, autonomous WiMon 100 unit comprises a vibration
sensor, temperature sensor, long-life battery and a WirelessHART radio.
WiMon 100 was jointly developed by ABB researchers in Norway and
Sweden, in cooperation with SKF Reliability Systems and SINTEF (an independent
research organization based in Norway). The project received financial
support from the Research Council of Norway through its Petromaks and
DEMO2000 programmers, as well as from several oil companies including
Statoil and BP.
Due to the cost efficiency, small size and ease of mounting and installation
of the WiMon 100 sensor, continuous vibration monitoring can be realized for
all types of rotating machines. WiMon 100 units form a mesh communication
network; providing a secure, reliable and redundant path from WiMon 100
sensor to a gateway and onwards to monitoring and analysis tools (the central
system). The central system (PC, network, DCS…) performs the necessary
data analysis and storage and makes data available in real time.
The system (visualized in Figure 3.23) also contains a WirelessHART
gateway that coordinates the sensor communication and manages the network
security. The gateway device converts wireless device data to a format that is
compatible with the wired automation systems.
A WiMon Data Manager provides the following main functionalities: a system
browser, a system for commissioning and maintenance support (including
firmware upgrade), automated data acquisition and storage of waveforms and
dynamic data (velocity, envelope and temperature) in an OPC server, an operator
interface for showing vibration waveforms and trends and temperatures
and a waveform export tool for the interfacing of analysis packages like the
ABB Analyst.
